Book 3 in the #1 bestselling Wishes Series The only way to move forward was to go back to the very beginning…. After three miserable weeks without Charli, Adam makes the decision to follow her, desperately hoping to find a way of following through on his promise of a happy ending. He finds her back in Pipers Cove, healing her broken heart by spending time with the one person who never lets her down. Both know nothing has changed. They're desperately in love, hopelessly stuck in limbo, and unable to find common ground. When fate offers them a chance at a different kind of ending, it’s a one-shot deal. Running with it means changing their plans – something neither of them has ever been willing to do before, even for each other. Just as one begins to find their way, the other completely loses direction – and neither of them realise that time is running out.
Cheryl Claassen offers an authoritative, readable and clear guide to the study of shells, which is addressed to students and professional archaeologists and palaeontologists. She considers the history of archaeological interest in shells, the biology of freshwater and marine molluscs, and critically discusses current techniques, methods, and research problems. Drawing on examples worldwide, and covering prehistoric and historic periods, among the topics covered are: is shell deposit natural or cultural? How long do shells last? What can shells tell us about the environmental characteristics and ancient habitats or about the people who collected them? What symbolic roles have shells served in human societies? This is a well balanced account, and all aspects of the subject are clearly represented.
Taphonomic bias is a pervasive feature of the fossil record. A pressing concern, however, is the extent to which taphonomic processes have varied through the ages. It is one thing to work with a biased data set and quite another to work with a bias that has changed with time. This book includes work from both new and established researchers who are using laboratory, field and data-base techniques to characterise and quantify the temporal and spatial variation in taphonomic bias. It may not provide all the answers but it will at least shed light on the right questions.
This collection of conference papers presents information on the molecular genetics, biomineralization, growth and ecology of extant brachiopod stocks (extrapolated back to the Cambrian), and the shell microstructure, taphonomy, paleogeography, evolution, and taxonomy of fossil brachiopods.
Ring Current Investigations offers a comprehensive description of ring current dynamics in the Earth's magnetosphere as part of the coupled magnetosphere-ionosphere system. In order to help researchers develop a deeper understanding of the fundamental physics of geomagnetic storms, it includes a detailed description of energetic charged particles injection, trapping, and loss. It reviews historical and recent advances in observations, measurements, theory and simulations of the inner magnetosphere and its coupling to the ionosphere and other surrounding plasma populations. In addition, it compares the physics of ring currents at other strongly magnetized planets in the solar system, specifically Jupiter, Saturn, Uranus and Neptune, with the ring current system at Earth. Providing a description of the most important space weather effects driven by inner magnetospheric energetic particles during geomagnetic storms and present capabilities for their nowcast and forecast, Ring Current Investigations is an important reference for researchers in geophysics and space science, especially related to plasma physics, the ionosphere and magnetosphere, solar-terrestrial relations, and spacecraft anomalies. - Includes an appendix with links to downloadable video clips, illustrating features of ring current and geomagnetic storm dynamics - Provides overview of existing state-of-the-art numerical models and links for open-source code downloads - Offers guidance on how to develop numerical models within the context of the present-day understanding
Morphodynamics is defined as the unique interaction among environment, functional morphology, developmental constraints, phylogeny, and time—all of which shape the evolution of life. These fabricational patterns and similarities owe their regularity not to a detailed genetic program, but to extrinsic factors, which may be mechanical, chemical, or biological in nature. These self-organizing mechanisms are the focus of Morphodynamics. Illustrated by numerous examples from across the biological spectrum, this book embodies the foundation of noted paleontologist Adolf Seilacher’s thinking on the study of morphodynamics. It represents his unique approach of presenting paleontology from an ecological and constructional perspective, rather than a purely taxonomic one. The hallmark of Seilacher’s storied career has been a constructional and functional focus. He begins by discussing the basic principles—form, pattern formation, ecology and evolution, as well as the factors that override those processes. Next, he examines how morphodynamic principles are implemented in various invertebrates including single-celled protists, Ediacarans, sponges, coelenterates, shelled organisms, worms, arthropods, and echinoderms. The final chapter explores how morphogenetic principles may apply to clonal colonial organisms. Summarizing seventy years of research into the interactions of form, function, and evolution, the book is copiously illustrated with the author’s own distinctive drawings and an abundance of photos. It provides a framework for readers to pose their own questions and sharpen their interpretive skills on this fascinating topic.
The first palaeoecology book to focus on evolutionary palaeoecology, in both marine and terrestrial environments. Discusses reconstruction of the past ecological world at population, community and biogeographic levels. A well-illustrated and substantial volume giving accessible coverage of the full range of subjects within palaeoecology. Reviews and summarises all the major mass extinctions.
"This is the major text on the integration of field palaeontology and sedimentology, particularly valuable for both practical lab exercises and students working independently and unsupervised on field projects" Reviewer's comment Field Palaeontology provides a comprehensive, rigorous and unique approach to the analysis of fossils and sediments and offers a practical field guide which no palaeontology student can afford to be without. The past decade has seen immense changes in palaeontology and in the study of sedimentary rocks in general. This edition has been thoroughly revised to take into account these advancements in the subject to produce a book that is unique in its coverage of palaeontology and sedimentology. It aims to provide a basis for evaluating the information potential of fossiliferous sediments, and then to give an outline of the strategy and tactics whicn can be adopted in the field. Field Palaeontology is written for advanced undergraduate courses in palaeontology, palaeoecology, palaeobiology, sedimentology and biostratigraphy within geoscience and geology degrees. It is also useful reading for Masters earth science students and first year postgraduates looking for a grounding in the basics of the subject.
